Saws

Discover our range of high-quality RUKO metal saw blades for precise and efficient cutting work on metal. Metal saw blades play a key role in determining the cut quality, service life and cost-effectiveness of cutting work. Choosing the right saw blade depends, among other things, on the material, the material thickness, the tooth pitch and the type of tooth profile. Depending on the application, different saw blades are used for jigsaws, reciprocating saws or hand saws.

In metalworking, mechanical engineering and installation technology, specially designed metal saw blades enable precise cuts and cost-effective material processing. The requirements vary depending on the material, material thickness and area of application.

Thanks to optimised tooth geometries, high-quality materials and precise manufacturing, RUKO metal saw blades offer a long service life and reliable performance, even when cutting demanding materials.

The saw blade carries out the actual cutting work and is largely responsible for the quality of the cut, service life and cutting speed. Its performance is determined primarily by the material, the tooth geometry and the tooth pitch.

During sawing, the individual teeth engage with the material and remove chips. This cuts the workpiece along the desired cutting line. Depending on the application, different metal saw blades are used for jigsaws, sabre saws or hand saws.

The right combination of saw blade, material and tooth profile ensures precise cuts, controlled chip formation and a long service life.

Metal saw blades are used in many areas where materials need to be cut or trimmed reliably.

Metalworking

• Cutting steel sections and metal pipes
• Cutting sheet metal or semi-finished products to size
• Pre-processing workpieces for milling or turning operations

Mechanical and plant engineering

• Cutting raw materials to length
• Cutting structural elements
• Adjusting components during assembly

Installation and Assembly

• Cutting pipes and sections to length
• Adjusting metal components on construction sites
• Preparing components for fitting or assembly

Reliable tools with a long service life are particularly important, especially for assembly work. This makes metal saw blades one of the key factors for precise cutting operations in metalworking.

Different saw blades are used depending on the workpiece, material thickness and application. In professional settings, jigsaws, sabre saws and hand saws are the most commonly used tools.

Jigsaws

Jigsaws use narrow, vertically moving jigsaw blades that are particularly suitable for precise contour cuts or cut-outs.

Typical applications include:

• Cutting-outs in sheet metal
• Modifications to housings
• Contour cuts during assembly work

Different tooth pitches and materials such as HCS or HSS bimetal allow various metals to be machined reliably.

Reciprocating saws

Reciprocating saws, which use a back-and-forth motion for the saw blade, are often used for quick cutting jobs. They are particularly suitable for heavy-duty applications in metalwork, during dismantling work or on construction sites.

Reciprocating saws are sometimes also referred to as sabre saws or tiger saws – these are different names for the same type of saw.

Typical applications for reciprocating saw blades include:

• Cutting pipes and sections
• Dismantling metal structures
• Cutting to size during installation work

Sturdy sabre saw blades also allow thicker materials or multi-layered workpieces to be cut.

Hand saws

Hand saw blades are fitted into saw frames and are mainly used for manual work in workshops or during assembly. They enable controlled cuts without the need for power tools.

Typical applications include, for example:

• Manual cutting of metal sections
• Minor adjustment work
• Precise cutting during assembly or repair

Hand saw blades are often made from HSS/HSS-Co or bimetallic materials, which gives them high wear resistance.

The type of saw used depends primarily on the material, material thickness, cut shape and the tools available.

For precise results, the manufacturer’s specifications should be followed.

Choosing the right saw blade also plays a crucial role here.

Material

Different materials place different demands on the tool.

Typical materials:

• Steel
• Stainless steel
• Aluminium
• Non-ferrous metals

Harder materials require more durable cutting materials and adapted tooth geometries.

HSS bimetal saw blades for heavy-duty applications

HSS bimetal saw blades are frequently used for demanding materials and heavy-duty applications.

The teeth of the saw blade are made of HSS steel, whilst the back is made of a softer and more elastic HCS steel.

This combination of materials enables HSS bimetal saw blades to achieve high flexibility combined with high cutting performance and a long service life.

Advantages:

• Long service life
• High resistance to breakage
• Suitable for demanding metalworking applications
• Reliable performance under varying loads

Material thickness

The thicker the material, the higher the cutting forces and heat generation. Thin sheets can often be cut without difficulty using finely-toothed saw blades, whilst thicker materials require more powerful machines or coarser tooth pitches.

Choosing the correct tooth pitch for metal saw blades

The tooth pitch affects cutting quality, chip removal and the service life of the saw blade.

To prevent teeth from breaking off or the saw blade from snapping, at least three teeth should always be in contact with the material at any one time. Whether a coarse- or fine-toothed saw blade should be used depends on the thickness of the material being cut.

As a guide:

For optimum results, a number of basic factors should be taken into account:

• Select an appropriate cutting speed
• Use a steady feed rate
• Securely clamp the workpiece
• Use coolants and lubricants where necessary

These measures increase tool life, cut quality and process reliability.
